DIY: Floor Plate Tripod for Low Angle Shots
That's why Burger put together an inexpensive floor plate tailored specifically for his needs. It cost $20 in all and it's simple enough. You'll need a piece of steel, a piece of wood , a bit of scrap rubber and some epoxy.
To ensure complete stability, Burger says that you'll need a bit of welding done. He swung over to a local metal shop to have the job done.
Check out the full tutorial including a great animation of the project being assembled over at DIY Photography.
